Greetings...

Can anyone provide me with a supplier for the o-rings used at the vial  
connection points on the Kiel Device?  We have been using o-rings from  
Marco Rubber for the past few years, but now upgraded from a Kiel III  
to a Kiel IV device.  We are running a few degrees hotter with the  
Kiel IV, and the phosphoric acid that I'm using is slightly stronger  
(density of 1.94 g/cm3 instead of 1.92 g/cm3).  Due to one or both of  
these factors, the viton o-rings from Marco quickly degrade...don't  
last a whole run before I have crashes due to high leak rates.

Anyone know of suppliers out there carrying different/better quality  
of o-rings?

Thanks...
